I'm already two weeks after my third TCA Cross treatment but it looks to me that the acne scars seem to be worse. Some of them which have been flattened seems to be bumpy again. There was a yellowish spot a few days after the treatment and I also did use essence and serum boosters a week after the treatment. Could that have been a cause? Can the new skin produced through TCA Cross treatment erode from using essence and serum boosters? Or is it normal that skin looks worse after each TCA Cross treatment before it gets better?
